MACHINE FORv PAGING BOOKS.

Speccatonof Letters Patent No.

To all 'whom t may concern Be it known that LHENRY Hoorrs'rnassnn, ofthe city and count-y of Philadelphia and State of Pennsylvania, haveinvented a new and useful Improvement in Paging-Machines for the Purposeof Paging Books; and I do declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had t-o the annexed drawings, making a part of thisspecification, in which- Figure 1 is a perspective view; Figs. 2 and 3sectional drawings. 1

'Io enable others skilled in the art, I will proceed to describe itsconstruction and operation.

I construct the body of my machine of wood somewhat of the form of adesk or table, (A) with the bottom extended to the left (B B B) for thepurpose of receiving the shaft upon which the wheel (or form) slides andturns. The wheel is made of metal and of a spiral form, (C Fig. l) forthe purpose of paging an indefinite number of sheets. This is oneadvantage my improvement has over the machines now in use as they haveto use several forms (wheel chains7 &c.,) to complete the paging of onebook. At the outer edge of the flange of the form there are spaces cut;(D) these spaces correspond with and are the same distance apart as thetype on the surface of the fiange. These spaces have a two-fold use; oneis they will not allow the wheel (or form) to move any farther than isrequisite, as the roller (E Fig. 2) upon which the liange of the formrests partly enters the spaces, and holds it in that position until itismoved by an adjustable escapement (F) acted on by a treadle (G Fig. l)with the foot. The escapement is another advantage I have, as it mattersnot how rapid the machine is worked the momentum cannot throw it fartherthan is necessary; as is the case with the ratchet wheel, as theescapement with unerring certainty moves it just so far and no farther.The adjustable part of the escapement working on a center is always whenout of the spaces, at an angle (I Fig. 3) with the next succeedingspace.; and being of a wedge shape at its point forms an inclined planeupon. which t-he sides of the spaces bear; and by its upward motionmoves the form the distance of one space only. When it moves downward inthe act of printing, the upper part of the escape- 11,728, datedSeptember 26, 1854.

ment (J Figs. 2 and 3) enters the space at the saine time the adjustablepart leaves it and prevents the form being moved while in the act ofprinting. At the upper end of the stationary part of the escapement anarm is attached (K Figs. 2 and 3) by an adjustable screw nutso that itcan be raised or lowered at pleasure. This is directly over the type andin descending presses the leaf on the type and prints the even numbers;and there is a corresponding arm (L Fig. 3) which at the same time movesupward and presses against the type on the lower surface of the flange,that prints the odd numbers, so that two numbers are printed at the sametime.

The spiral wheel (or form) moves on a vert-ical shaft (M Fig. l) and hasa joint at its lower end (N) with a stop. And a brace (O) proceeds fromthe main body of the machine and receives the upper end of the shaft (P)sothat when the spiral form has run down, or as far as requisite byreleasing the brace the form can be removed away from the escapement,andother machinery,

and raised to its first position in readiness Motion is given to themachinery by pressure of the foot upon a treadle (G Fig. 1) to print,and by a counter weight (Q Figs. 2 and 3) at the opposite end of thetreadle an upward motion is given which causes the escapement to movethe form and inking rollers (R R Fig. 2). At the same time the rollersmove they ink the type. An iron shaft proceeding from the treadleconnects with a crank (S Figs. 1, 2 and and gives the requisite motionto the connecting rods which works the escapement, the arms, the inkingrollers, the smut, &c.

The type are to be riveted on the flange in sect-ions containing severalnumbers in each section; or to have type with a face on each end and tobe placed in square holes in the flange with the upper part of the holeslargest and the type to correspond so they will not drop through. Inthis way they will adjust themselves to the arms in the act of printing;and can be easily placed, and replaced.

N. B.-Tlie vertical shaft which supports the form has a spiral groovewhich corresponds with the spiral of the flange; and if desired can oerused instead of the above de- Frst, the adjustable escapement F; anderbed. I adopt the roller as preferable, as second',A the roller E inconnection with the it matters not how untrue the form may be spacessubstantially as herein described.

it will cause the type always to be n their HENRY HOCHST'RASSER. 5proper place. Witnesses:
